Findings of excess cardiometabolic morbidity and mortality in persons with severe mental illness (SMI) have led to a growing interest by Community Mental Health Centers (CMHCs) in improving the medical care of the populations they treat. However, these organizations face a number of financial and organizational barriers to implementing and sustaining such programs. In previous and ongoing work, the study team has documented the promise of team-based models in improving health and health care in this population. This study will test a novel approach for improving mental health consumers based on a partnership model between a CMHC and a Community Health Center (CHC). This partnership will capitalize on collocation of services, the primary care expertise of the CHC, and favorable reimbursement conditions, to develop a program that is both clinically robust and financially and organizationally sustainable A total of 300 CMHC clients with a severe mental illness and one or more active cardiometabolic problem (diabetes, hypertension, hyperlipidemia) will be randomized to either onsite Integrated Community Care (ICC) (n=150) or to a referral to the partner community health center (CHC) (n=150) for their medical problems. For those in the ICC, the CHC will establish a satellite clinic at the CMHC staffed by a physician assistant and care manager. The ICC will provide care for both the index cardiometabolic conditions and common acute and chronic comorbidities.
